All parents are bound to disagree, argue or even raise their voices with each other.

But psychologists say parents can minimize the negative impact of their arguments on their children. It's just a matter of using a few simple techniques to turn down the heat and repair the damage after it's over.

Psychologist Suzanne Phillips at Long Island University says one of the most important things for parents to remember when they're on the verge of a big argument is not to involve the child.

For years now, psychologists have been telling couples who yell at one another to stop for the sake of the kids. Such conflict in the home — even when no violence is involved — is associated with a host of negative behavioral and life outcomes for children.

From the first explosion in Boston on Monday to the second, just 15 seconds elapsed. And in those 15 seconds, three people were mortally wounded, including an 8-year-old boy. The number of injured topped 100, and for those of us watching, it was a profound reminder of a reality we'd prefer to ignore.

It may cost less to do business in places where there's what some people call a culture of health. And that's put Colorado, which has the lowest rates of adult obesity in the country, on the map for companies looking to relocate or expand.

Kelly Brough is making the most of it. She runs the Denver Metro Chamber of Commerce, and she's creative about luring businesses to relocate to Colorado. She runs a "Colorado loves California" campaign, for instance.

A federal judge in Brooklyn, N.Y., has ruled that the morning-after pill for emergency contraception must be made available over the counter to girls 16 and under.

The ruling could end a more than decade-long battle over how easy or difficult it should be for teenage girls to obtain emergency contraception. The ruling would also make it easier for older women to obtain the drug because it wouldn't have to be kept behind drugstore counters anymore.

Camden, N.J., has serious health problems, with too many people going to local emergency rooms unnecessarily. But progress is being made, albeit slowly.

John Pike, 53, is a Camden resident who used to be a frequent flier at the ER.

Pike has a smoker's cough, and when that cough or pain in his bad hip flared up, he'd go to the ER — maybe eight or nine times a year. But when he did, ER staffers didn't really remember him or his medical history.

President Obama has announced an ambitious plan to explore the mysteries of the human brain.

In a speech Tuesday, Obama said he will ask Congress for $100 million in 2014 to "better understand how we think and how we learn and how we remember." Other goals include finding new treatments for Alzheimer's disease, epilepsy and traumatic brain injury.

Last week, scientists announced they had sequenced the full genome of the most widely used human cell line in biology, the "HeLa" cells, and published the results on the web. But the descendents of the woman from whom the cells originated were never consulted before the genetic information was made public, and thus never gave their consent to its release.

For the first time since the government started tracking the disease in the 1950s, the number of annual TB cases has dropped below 10,000, the Centers for Disease Control and Prevention said Thursday in the Morbidity and Mortality Weekly Report.

So when doctors at Children's Hospital in Boston noticed they kept seeing an unusually high number of asthmatic kids from certain low-income neighborhoods, they wondered if they could do something about the environment these kids were living in.

Wisconsin has the highest number of binge drinkers in the nation — one in four adults. And binge drinking — defined as five or more alcoholic drinks in a short period of time for men, and four for women — cost the state $6.8 billion in 2012.

That breaks down to about $1,200 per person in higher taxes, more health care, and other costs, according to a new study from the University of Wisconsin Population Health Institute.

If aging is not for sissies, that's especially true if you're homeless. You can be on your feet for hours, or forced to sleep in the frigid cold or seriously ill with no place to go. But, increasingly, the nation's homeless population is getting older. By some estimates, more than half of single homeless adults are 47 or older.

And there's growing alarm about what this means — both for the aging homeless and for those who have to foot the bill. The cost to society, especially for health care and social services, could mushroom.

There's a kind of rice growing in some test plots in the Philippines that's unlike any rice ever seen before. It's yellow. Its backers call it "golden rice." It's been genetically modified so that it contains beta-carotene, the source of vitamin A.

Bacon and bologna are hardly health food. But a huge new study offers the strongest evidence yet that eating processed meat boosts the risk of the two big killers, cancer and heart disease.

A multinational group of scientists tracked the health and eating habits of bacon-loving Brits, wurst-munching Germans, jamon aficionados in Spain, as well as residents of seven other European countries — almost a half-million people in all.

Federal officials warned Tuesday that an especially dangerous group of superbugs has become a significant health problem in hospitals throughout the United States.

These germs, known as carbapenem-resistant Enterobacteriaceae, or CRE, have become much more common in the last decade, according to the Centers for Disease Control and Prevention. And the risk they pose to health is becoming evident.

Scientists believe a little girl born with HIV has been cured of the infection.

She's the first child and only the second person in the world known to have been cured since the virus touched off a global pandemic nearly 32 years ago.

Doctors aren't releasing the child's name, but we know she was born in Mississippi and is now 2 1/2 years old — and healthy. Scientists presented details of the case Sunday at a scientific conference in Atlanta.

Robert Lustig wants to convince the world that sugar is making us very sick. And lately he's turned to an unconventional field – econometrics – to do it.

Lustig rounded up statisticians and epidemiologists to look at the relationship between food and diabetes risk. The paper, published this week in the journal PLoS One, found that the more sugar on the market in 175 countries, the higher the country's diabetes rate.

When NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health asked parents and caregivers in our new poll whether getting a good night's sleep is important, families overwhelmingly told us that sleep is a high priority.

But almost all said that it's difficult to pull off. And studies suggest this is especially true for teenagers.
